Main Printed Circuit Assembly (PCA)
The Auto-V function is a logic-driven feature where the ASIC must differentiate between signal frequencies and toggle the LoZ shunt circuit. A failure in this specific mode indicates the processor can no longer actuate the internal impedance switch or is receiving out-of-range data from the input protection block. Because these components are integrated into the primary board, a PCA replacement is the only reliable method to restore the calibrated logic and switching hardware.
